Revised Coalbed Methane Maps

The Wyoming State Geological Survey (WSGS) has completed revised versions of their coalbed methane (CBM) maps of the Powder River Basin, Wyoming. Three maps that show CBM development activity in this basin are now available as WSGS Map Series (MS)-56, MS-57, and MS-58, replacing all previous versions of what were known as Coalbed Methane Maps (CMMs). Now part of the WSGS numbered map series, each new map contains updated CBM permit information, drilling, production, and other development activities through February 5, 2003 and is available in either hard copy or digital form. Also included are major natural gas pipelines, compressor stations, gas plants, coal outcrop and overburden information, coal leases, railroads and spur lines, and land ownership.

MS-56 is entitled Coalbed methane activity in the eastern Powder River Basin, Campbell and Converse Counties, Wyoming, by R.H. De Bruin, R.M. Lyman, L.L. Hallberg, and N.R. Jones, and replaces CMM 02-4 published in September, 2002. A full color, plotted map measuring 36Ó x 60Ó at a scale of 1:126,720 (1Ó=2 miles) is available (rolled only) for $30.00 (add $6.00 for shipping and handling; Wyoming addresses must include 6% sales tax). The digital data for this map is available on the CD-ROM for MS-58 (below).

MS-57 is entitled Coalbed methane activity in the western Powder River Basin, Campbell, Converse, Johnson, Natrona, and Sheridan Counties, Wyoming, by R.H. De Bruin, R.M. Lyman, L.L. Hallberg, M.M. Harrison, and N.R. Jones, and replaces CMM 02-5 published in September, 2002. This is also available as a full color, plotted map measuring 36Ó x 60Ó for the same price as MS-56; the digital data is also on the CD-ROM for MS-58 (below).

MS-58 is entitled Coalbed methane activity in the Powder River Basin, Wyoming, by R.H. De Bruin, R.M. Lyman, L.L. Hallberg, M.M. Harrison, and N.R. Jones, and replaces CMM 02-6 published in September, 2002. This full color, plotted map is a reduced and combined version of MS-56 and MS-57 that measures 36Ó x 45Ó at a scale of 1:250,000 (1Ó~ 4 miles) and is available (rolled only) for $40.00 (add $7.50 for shipping and handling; Wyoming addresses must include 6% sales tax), or laminated for $50.00 (add $8.50 for shipping and handling; Wyoming addresses must include 6% sales tax).

Digital data for the eastern and western Powder River Basin maps and the combined map are available on the CD-ROM of MS-58. ESRI¨ Shapefiles (in a number of layers that can be toggled off or on) are supplied, as well as ESRI¨ ArcReaderª and LizardTech© MrSID Geo Viewer¨ software included for viewing the maps. The CD sells for $50.00 (add $8.50 for shipping and handling; Wyoming addresses must include 6% sales tax).

The three maps are available over-the-counter at the WSGS office in Laramie or can be ordered by phone, fax, or Email.
